GG-1AF (Z) High voltage switch board (switch board), is applicable
for 3.6~12kV, three-phase AC 50Hz single main circuitry systems and
single main circuit with bypass systems in power plants,
transformer substations, and factories. It's used for receiving and
distributing powers, meanwhile control, inspect, and protect the
circuit. The product is provided with a perfect, reliable,
convenient closedown functions, so-called "Five Preventions":
1.1 Prevent turning on/off the isolated switches with load.
1.2 Prevent entering the electriferous isolating rooms by mistake.
1.3 Prevent turning on/off the breakers by mistake.
1.4 Prevent transmitting electricity with earth-wire.
1.5 Prevent touching earth-wire with electricity.
1. Natural application conditions
A. Altitude level under 1000m
B. Air temperature: Upper limit +40 Lower limit -10 in common
place, -25 in cold place.
C. Relative humidity: Monthly mean value less than 90%; Daily mean
value less than 95%;
D. No electric dust, corrosive air or steam around.
E. No explosion or fire threatened.
F. No acute vibration.
2. Special working conditions
To install the switchboards above 1000m in altitude, it's necessary
to consult with manufacturers first. When ambient temperature above
the set value, compulsory ventilation in board is necessary, so as
to increase the carrying capacity of main circuit and branches.
When switchboard is working under high temperature or great
changing temperature, condensation may occurs, so heaters must be
installed to prevent accident or corrosion.&
